Class Summary Class Description ASCII85Filter Decodes data encoded in an ASCII base-85 representation, reproducing the original binary data.ASCII85InputStream This class represents an ASCII85 stream.ASCII85OutputStream This class represents an ASCII85 output stream.ASCIIHexFilter Decodes data encoded in an ASCII hexadecimal form, reproducing the original binary data.CCITTFaxDecoderStream CCITT Modified Huffman RLE, Group 3 (T4) and Group 4 (T6) fax compression.CCITTFaxDecoderStream.Node CCITTFaxDecoderStream.Tree CCITTFaxEncoderStream CCITT Modified Group 4 (T6) fax compression.CCITTFaxEncoderStream.Code CCITTFaxFilter Decodes image data that has been encoded using either Group 3 or Group 4 CCITT facsimile (fax) encoding, and encodes image data to Group 4.CryptFilter Decrypts data encrypted by a security handler, reproducing the data as it was before encryption.DCTFilter Decompresses data encoded using a DCT (discrete cosine transform) technique based on the JPEG standard.DecodeOptions Options that may be passed to a Filter to request special handling when decoding the stream.DecodeOptions.FinalDecodeOptions Helper class for reusable instances which may not be modified.DecodeResult The result of a filter decode operation.Filter A filter for stream data.FilterFactory Factory for Filter classes.FlateFilter Decompresses data encoded using the zlib/deflate compression method, reproducing the original text or binary data.IdentityFilter The IdentityFilter filter passes the data through without any modifications.JBIG2Filter Decompresses data encoded using the JBIG2 standard, reproducing the original monochrome (1 bit per pixel) image data (or an approximation of that data).JPXFilter Decompress data encoded using the wavelet-based JPEG 2000 standard, reproducing the original data.LZWFilter This is the filter used for the LZWDecode filter.Predictor Helper class to contain predictor decoding used by Flate and LZW filter.Predictor.PredictorOutputStream Output stream that implements predictor decoding.RunLengthDecodeFilter Decompresses data encoded using a byte-oriented run-length encoding algorithm, reproducing the original text or binary data -
